Geometrische Interpolation von Saugspannungsverteilungen

A procedure for interpolating the depth distribution of soil moisture tension A programmable procedure is described to compute hydraulic gradients from soil moisture tensions non-linearly distributed with depth. This interpolation-technique is based upon a geometrical procedure. Compared with other curve smoothing techniques it is flexible with respect to the given data constellation and requires a relatively small computational effort. This method is compared with that of cubic splines.
